A colleague configured new thin volumes on an EMC Symmetrix VMAX in preparation for a customer's Exchange 2010 environment. The Exchange environment will be configured on a 4-node Windows 2008 Failover Cluster. The customer's storage environment is already oversubscribed and the new store volumes are quite large. The colleague wants to avoid fully allocating the thin volumes.
How should you format the volumes?
A customer implemented an Oracle application on a VMAX with a mix of Enterprise Flash Drives (EFD) and FC 15K drives. EFD are configured in RAID 5 and FC 15K both in RAID 5 and RAID 1. The application is random read intensive. The customer has decided to place a portion of the database in each tier.
Which Oracle database files are suitable to be placed on EFD drives?
A customer wants to configure a virtual machine that can directly access PCI hardware I/O devices such as Network Interface Controller or Host Bus Adapter. Which CPU virtualization feature will you use to achieve the objective?
A colleague is demonstrating the VMAX virtual LUN migration feature. They configure four test devices to move from FC RAID 5 volumes to SATA RAID 6 volumes and start the migration. The colleague reports the LUN migration moves very slowly and appears to stop during peak processing times.
What is the likely cause of the issue?
A new data warehouse will be hosted on an existing 4-engine VMAX array. The database server has 4 HBAs connected at 8Gb/s. Due to limited SAN switch ports only port 0 on each VMAX FA is connected - also at 8Gb/s.
The workload is expected to require at least 1700MB/s of reads @ 128KB I/O size. It must maintain performance in case of any major component failure in the host, switch or array. Assume that the existing workload on the VMAX does not exceed 350MB/s per port. Also assume that the ports can sustain up to 500MB/s without exceeding 70% utilization.
What is the best practice HBA to FA mapping to ensure the required performance of the data warehouse?
